A study in the journal Cancer suggests that breast cancer patients who opt for lumpectomies with radiation might have a small survival advantage compared with those who have mastectomies. Dr. Mehra Golshan says it is hard to imagine that less surgery with radiation gives a better outcome.

WCVB-TV reporter and breast cancer survivor Kelley Tuthill is pregnant, and her oncologist, Dr. Ann Partridge, assured her studies show there is no link between pregnancy after successful treatment and recurrence.

A study led by Dr. Shoshana Rosenberg shows young women with cancer in one breast tend to overestimate their risk for getting cancer in the opposite, healthy breast -- sometimes driving them to have that breast removed.

In a 2013 study conducted by Shoshana Rosenberg, ScD, women younger than 40 with no increased genetic risk and disease in one breast believed that within five years, 10 out of 100 of them would develop it in the other.
